You'll never have to worry about slow drainage or clogs with this ball scupper from Flow-Max™. With a large 1-1/8" drain, it provides faster, more efficient drainage than similar products. And when debris does accumulate, all you have to do is twist it off to remove the obstructions, then slip it back into place. The ball scupper replaces worn-out flapper scuppers, and it easily retrofits all hole patterns. Each comes with a stainless steel lock screw for safety, and it is seal-slotted to fit over a 1-1/4" motorwell tube. The scupper is clear-colored.
